UL 1072 is a standard developed by Underwriters Laboratories (UL) that covers medium voltage cables for use in power distribution systems. The standard specifies the construction, materials, and testing requirements for these cables to ensure their safe and reliable operation.
"100% insulation" refers to the insulation material used in the cable, which is expected to provide complete coverage and protection for the conductors. In the case of 500mcm XLPE (cross-linked polyethylene) insulation, it means that the insulation layer completely surrounds the conductors, leaving no exposed areas.
XLPE is a commonly used insulation material for medium voltage power cables. It offers excellent electrical properties, thermal resistance, and moisture resistance, making it suitable for various applications.
The "PVC sheath" refers to the outer protective layer of the cable. PVC (polyvinyl chloride) is a durable and cost-effective material used for cable sheathing. It provides mechanical protection, as well as resistance to chemicals, sunlight, and abrasion.
Overall, a power cable with 100% insulation and 500mcm XLPE insulation with a PVC sheath, in compliance with UL 1072, would be designed for medium voltage power distribution, offering reliable electrical insulation, mechanical protection, and environmental durability.
